This is what I did; I ranked a brand new (never before registered) domain for a very easy 4-word keyword, and sat it at #1 for about a month. I then redirected it to a site in a completely different and totally unrelated niche that had been hanging around #9 for about 4 months (KW with many thousands of searches and highly profitable). The target site jumped to #1 in 3 days. Now, note that that 301 site only had two single-page 2.0's linking to it, each with about 300 words - that's it. I have no other way of explaining the sudden #1 jump, except that the 301 had more 'authority' because it had come from a #1 ranking spot already - even though it was a totally unrelated keyword (like, really unrelated; eg one about cars and the other about toothbrushes). Maybe a new method, then, is to rank for a super-easy keyword, let it mature there for 30-60 days, then 301 to any money site... I'm now trying to repeat this result a couple more times, to have proof of concept, rather than just a suspicion.
